About Me
I'm a backend-focused engineer based in Toronto. Over the past 3+ years I've worked on billing platforms, cloud microservices, automation frameworks, and API infrastructure at the Government of Ontario and Affimintus Technologies.
At Affimintus I built production REST APIs and full-stack systems with Java, Spring Boot, React, PostgreSQL, and MongoDB. At the Government of Ontario I built automation frameworks, API testing systems, and CI/CD pipelines. The through-line is software that other people depend on.
I graduated from Seneca Polytechnic with a 3.6 GPA Honours in Computer Programming & Analysis. I also teach coding to kids at Code Ninjas — it's a good way to stay sharp on fundamentals.
Outside of work I'm usually speedrunning Resident Evil 4 or diving into whatever new tech caught my attention that week.
Production backend thinking: API design, cloud infrastructure, testing discipline, and CI/CD automation.
Currently looking for backend SWE roles in Toronto.
